How it started

Formation and pre-merger

Infinity was founded in 1972 by two former Metromedia executives Michael A. Wiener and Gerald Carrus, with the acquisition of KOME, an FM radio station that served the San Francisco Bay Area, and finally received its license by the Federal Communications Commission (FCC) a year later. In 1979, Infinity acquired WBCN in Boston.

In 1981, Mel Karmazin was brought in as new president. Karmazin oversaw the operation of New York's WNEW-AM (now WBBR) and WNEW-FM for Metromedia. Soon after, the company acquired fellow New York stations WNEW-FM, WKTU (now WINS-FM; the present-day WKTU is owned by iHeartMedia), WZRC, and WFAN the following years, followed by WYSP-FM in Philadelphia. In 1983, Infinity absorbed KXYZ in Houston and WJMK and WJJD in Chicago.

Infinity became a publicly traded company in 1986. Within a year, it had purchased six more stations: KROQ-FM in Los Angeles, WJFK-FM in Washington, D.C., WQYK-AM/FM in Tampa, and KVIL-AM/FM in Dallas.

Karmazin and three other company executives took the company private in 1988 and took it public again in 1992. In 1993, Infinity was expanded to 22 radio stations.
